Where are you guys sourcing your Thumler's Tumbler (Model B) from? Doesn't appear that any of the sponsors are selling these machines and Cabelas Canada and USA are on back order.
Canadiantreasureseekers.com is the outfit that carries Thumler tumblers. I ended up buying a Lortone QT-12 from them because they didn't have a Thumler Model B in stock. Either one is a quality tumbler.
Like already said, make sure to get the hi speed motor.
Rock polishing demands low speed motor and ceramic media.
The motor can be swapped out I am told.
What kind of soap you guys using?
How much water?
